Question
The dome-shaped tortoise came from which islands?
- Pinta
- Hawaiian
- Isabela
- Hood
Hint:
Dome shaped tortoises are comparatively larger tortoise. their body is covered with a round shell.
The correct answer is: Isabela
- Marine turtles are found in Hawaiian Islands.
- Giant tortoises are found in Pinta and Hood islands.
- Dome shaped tortoises are found in Isabele Island.
- These are found in moist areas and are adapted to feed on vegetation that is closer to the land.
- Darwin noticed some differences among tortoises that he found in Galapagos Island and other islands. These were different in size and shape.
- These differences of tortoises supported the theory of natural selection.

How many species of finches were observed by Darwin on the Galapagos?
- While traveling through the island, Darwin noticed some birds.
- These birds had different sizes and shapes of their beak.
- The structure of their beak was changed due to adaptations.
- All of these birds were evolved from same ancestors. Just their beak was different.
- The shape of their beak was changed according to their feeding habits.
- So, he observed 13 such finches.

______________ is a force that causes groups of organisms to change over time.
- A group of organism changes overtime because of variations.
- These variations are caused during sexual reproduction.
- Changes are also caused by mutations. These are sudden changes that are caused on genetic level.
- So, all these changes caused in a group of organisms are developed in next generations only if these are helpful for them to survive in the changing environment.
- This is called adaptation. Only such changes are developed in generations of organism that helps them to evolve.
- So, nature selects only those who can survive better in the changing environment. This is called natural selection.
- This concept was given by scientist Charles Darwin. So, natural selection acts as a force that causes group of organisms to change overtime.
